<code>data.frame</code> with the following fields<ul>
<li><code>death</code>: age-independent daily probability of death</li>
<li><code>death_mean</code> and <code>death_sd</code>: age-dependent daily probability of death (<code>death_sd=0</code> indicates fixed life time (defined by <code>death_mean</code>))</li>
<li><code>dev</code>: age-independent daily probability of development</li>
<li><code>dev_mean</code> and <code>dev_sd</code>: age-dependent daily probability of development (<code>dev_sd=0</code> indicates fixed development time (defined by <code>dev_mean</code>))</li>
</ul>

value
